Question

Write pseudo code for deleting element from the linked list at the beginning and at the end.

Answer 1

Answer:

We have discussed Linked List Introduction and Linked List Insertion in previous posts on singly linked list.

Let us formulate the problem statement to understand the deletion process. Given a ‘key’, delete the first occurrence of this key in linked list.

To delete a node from linked list, we need to do following steps.

1) Find previous node of the node to be deleted.

2) Change the next of previous node.

3) Free memory for the node to be deleted.
